Traveling wave solutions of the Burgers-Huxley equations
Luis Fernando Mello, Ronisio Moises Ribeiro
We study the traveling wave solutions of the Burgers-Huxley equation from a geometric point of view via the qualitative theory of ordinary differential equations. By using the Poin…

Global stability of the Lengyel-Epstein systems
Lucas Queiroz Arakaki, Luis Fernando Mello, Ronisio Moises Ribeiro
We study the global (asymptotic) stability of the Lengyel-Epstein differential systems, sometimes called Belousov-Zhabotinsky differential systems. Such systems are topologically e…

Bifurcation of Limit Cycles from a Periodic Annulus Formed by a Center and Two Saddles in Piecewise Linear Differential System with Three Zones
Claudio Pessoa, Ronisio Ribeiro
In this paper, we study the number of limit cycles that can bifurcate from a periodic annulus in discontinuous planar piecewise linear Hamiltonian differential system with three zo…
